Fusioncharts._Fallbackjschartwhennoflash() Not Working As Expected

We are trying to implement the FusionCharts._fallbackJSChartWhenNoFlash(); function to run javascript charts within any browser when flash is not available with version 3.2. We wrapped the FusionCharts.cs file to build our own assembly to stick into the GAC. So, I thought I would add the fallbackJSChartWhenNoFlash call inside the below function just above the call to instantiate the new chart ( new FusionCharts...). I have the highcharts.js and your jquery.min.js files inside the same directory as the FusionCharts.js file. In our case they are in a subdirectory off the main application root. I removed flash from my laptop to test. I cleared my cache, history, etc. from the browser. When I run the code, I get the image in place of the charts that states I'm missing a plugin. I read on another post to try to change the reference of the loadScript(baseURL+'highcharts.js') inside the FusionCharts.js file since my .js is in a subdirectory, but that did not work either. Any suggestions would be appreciated! Thanks. Patrick

 

private static string RenderChartALL(string chartSWF, string dataUrl, string dataStr, string chartId, string chartWidth, string chartHeight, bool debugMode, bool registerWithJS, bool allowTransparent, string bgColor, string scaleMode, string language)

{

__INIT();

 

// string dataprovider_js_code;

SetConfiguration("debugMode", boolToNum(debugMode));

SetConfiguration("registerWithJS", boolToNum(true));

// setup debug mode js parameter

int debugMode_js_param = boolToNum(debugMode);

// setup register with js js parameter

int registerWithJS_js_param = boolToNum(true);

string dataFormat = GetConfiguration("dataFormat");

dataFormat = (dataFormat == "" ? "xml" + (dataStr == "" ? "url" : "") : dataFormat + (dataStr == "" ? "url" : ""));

 

if (GetConfiguration("renderAt") == "") SetConfiguration("renderAt", chartId + "Div");

 

string wmode = GetConfiguration("wMode");

if (wmode.Trim() == "" || wmode == null)

{

wmode = allowTransparent ? "transparent" : "opaque";

}

 

SetConfiguration("swfUrl", chartSWF);

SetConfiguration("dataFormat", dataFormat);

SetConfiguration("id", chartId);

SetConfiguration("width", chartWidth);

SetConfiguration("height", chartHeight);

SetConfiguration("wMode", wmode);

 

string dataSource = (dataStr == "" ? dataUrl : dataStr.Replace("\n\r", ""));

string dataSourceJSON = "\"dataSource\" : " + (dataFormat == "json" ? dataSource : "\"" + dataSource + "\"");

string chartConfigJSON = "{" + fc_encodeJSON(GetConfigurationGroup("params"), false) + "," + dataSourceJSON + "}";

 

StringBuilder builder = new StringBuilder();

builder.AppendFormat("<!-- START Script Block for Chart {0} -->" + Environment.NewLine, chartId);

builder.AppendFormat("<div id='{0}Div' >" + Environment.NewLine, chartId);

builder.Append("Chart." + Environment.NewLine);

builder.Append("</script>" + Environment.NewLine);

Hi Pdaniel,

Thanks for your post.

We are unable to reproduce the issue.

Could you please provide any live link or any sample HTML of your issue.

 

I just stepped through the FusionCharts.cs file in debug mode and it appears the code above does not get executed (RenderChartALL function). I assume this is why it's not working. Which function should I place the fallbackJSChartWhenNoFlash line of code in order for it to execute before the chart renders? when stepping through the code, the following function gets executed..

 

public static string RenderChartHTML(string chartSWF, string dataUrl, string dataStr, string chartId, string chartWidth, string chartHeight, bool debugMode, bool registerWithJS, bool allowTransparent)

{

return RenderChartHTMLALL(chartSWF, dataUrl, dataStr, chartId, chartWidth, chartHeight, debugMode, registerWithJS, allowTransparent, "", "noScale", "EN");

}

 

which then calls

 

private static string RenderChartHTMLALL(string chartSWF, string dataUrl, string dataStr, string chartId, string chartWidth, string chartHeight, bool debugMode, bool registerWithJS, bool allowTransparent, string bgColor, string scaleMode, string language)

{

__INIT();

 

string wmode = GetConfiguration("wMode");

if (wmode.Trim() == "" || wmode == null)

{

wmode = allowTransparent ? "transparent" : "opaque";

}

 

SetConfiguration("movie", chartSWF);

SetConfiguration("src", chartSWF);

SetConfiguration("dataXML", dataStr);

SetConfiguration("dataURL", dataUrl);

SetConfiguration("width", chartWidth);

SetConfiguration("height", chartHeight);

SetConfiguration("chartWidth", chartWidth);

SetConfiguration("chartHeight", chartHeight);

SetConfiguration("DOMId", chartId);

SetConfiguration("id", chartId);

SetConfiguration("debugMode", boolToNum(debugMode));

SetConfiguration("wMode", wmode);

 

string strFlashVars = FC_Transform(GetConfigurationGroup("fvars"), "&{key}={value}", true);

SetConfiguration("flashvars", strFlashVars);

 

string strObjectNode = "<object " + FC_Transform(GetConfigurationGroup("object"), " {key}=\"{value}\"", true) + " >\n";

string strObjectParamsNode = FC_Transform(GetConfigurationGroup("objparams"), "\t<param name=\"{key}\" value=\"{value}\">\n", true);

string strEmbedNode = "<embed " + FC_Transform(GetConfigurationGroup("embed"), " {key}=\"{value}\"", true) + " />\n";

 

 

StringBuilder htmlcodes = new StringBuilder();

htmlcodes.AppendFormat("<!-- START Code Block for Chart {0} -->" + Environment.NewLine, chartId);

htmlcodes.Append(strObjectNode + Environment.NewLine);

htmlcodes.Append(strObjectParamsNode + Environment.NewLine);

htmlcodes.Append(strEmbedNode + Environment.NewLine);

htmlcodes.AppendFormat("</object>\n<!-- END Code Block for Chart {0} -->" + Environment.NewLine, chartId);

 

// Re-Initializing...

__fc__initialize__();

 

return htmlcodes.ToString();

}

 

Should I place the fallbackJSChartWhenNoFlash inside one of these functions? thanks.

Not sure if this help as well, but when I step through the FusionCharts.cs file function, the following function returns back the variable value below it. As you can see I added in the FusionCharts._fallbackJSChartWhenNoFlash(); javascript code. Does this look correct?

 

private static string RenderChartHTMLALL(string chartSWF, string dataUrl, string dataStr, string chartId, string chartWidth, string chartHeight, bool debugMode, bool registerWithJS, bool allowTransparent, string bgColor, string scaleMode, string language)

{

__INIT();

 

string wmode = GetConfiguration("wMode");

if (wmode.Trim() == "" || wmode == null)

{

wmode = allowTransparent ? "transparent" : "opaque";

}

 

SetConfiguration("movie", chartSWF);

SetConfiguration("src", chartSWF);

SetConfiguration("dataXML", dataStr);

SetConfiguration("dataURL", dataUrl);

SetConfiguration("width", chartWidth);

SetConfiguration("height", chartHeight);

SetConfiguration("chartWidth", chartWidth);

SetConfiguration("chartHeight", chartHeight);

SetConfiguration("DOMId", chartId);

SetConfiguration("id", chartId);

SetConfiguration("debugMode", boolToNum(debugMode));

SetConfiguration("wMode", wmode);

 

string strFlashVars = FC_Transform(GetConfigurationGroup("fvars"), "&{key}={value}", true);

SetConfiguration("flashvars", strFlashVars);

 

string strObjectNode = "<object " + FC_Transform(GetConfigurationGroup("object"), " {key}=\"{value}\"", true) + " >\n";

string strObjectParamsNode = FC_Transform(GetConfigurationGroup("objparams"), "\t<param name=\"{key}\" value=\"{value}\">\n", true);

string strEmbedNode = "<embed " + FC_Transform(GetConfigurationGroup("embed"), " {key}=\"{value}\"", true) + " />\n";

 

 

StringBuilder htmlcodes = new StringBuilder();

htmlcodes.AppendFormat("<!-- START Code Block for Chart {0} -->" + Environment.NewLine, chartId);

htmlcodes.Append("<script type=\"text/javascript\">" + Environment.NewLine);

htmlcodes.Append("FusionCharts._fallbackJSChartWhenNoFlash();" + Environment.NewLine);

htmlcodes.Append("</script>" + Environment.NewLine);

htmlcodes.Append(strObjectNode + Environment.NewLine);

htmlcodes.Append(strObjectParamsNode + Environment.NewLine);

htmlcodes.Append(strEmbedNode + Environment.NewLine);

htmlcodes.AppendFormat("</object>\n<!-- END Code Block for Chart {0} -->" + Environment.NewLine, chartId);

 

// Re-Initializing...

__fc__initialize__();

 

//builder.Append("FusionCharts._fallbackJSChartWhenNoFlash();" + Environment.NewLine);

//string strHTML = "<script type=\"text/javascript\"><!--\n FusionCharts._fallbackJSChartWhenNoFlash();\n// --></script>";

//return (strHTML);

 

return htmlcodes.ToString();

}

 

 

The htmlcodes.ToString(); equals to.....

 

{<!-- START Code Block for Chart AssetCategoryChartControl -->

Does RenderChartHTML not handle _Fallbackjschartwhennoflash()? I believe we had called RenderChartHTML versus RenderChartt for a specific reason. I'm afraid by switching it, it could cause other issues. Is that the only way this works?

So I tried calling the Renderchart method and I get javascript errors now. I get the following message.. "Microsoft JScript runtime error: There was an error rendering the chart. Enable FusionCharts JS debugMode for more information." .I set the debugmode='1' but I still can't get rid of this message. I'm hesitant to contineu down this RenderChart method with the issues I'm hitting (unless I absolutely have to, to utilize the _Fallbackjschartwhennoflash.

Hi Pdaniel,

Thanks for you reply.

"RenderChartHTML " method directly write the embed/object code to add a flash object in a page. so when there has no flash it will so the plugins missing message.

Where as the JavaScript rendering is handled by the FusionCharts JavaScript rendering method, which checks if there has no flash and the users want to render the js chart if there has no flash then it render the chart in JavaScript mode.

But the "RenderChart" method write the JavaScript rendering method in the page which render the chart using JavaScript.

 

To debug the charts in JavaScript you may refer to this link http://www.fusioncharts.com/docs/Debug/JS.html

You might be using a Single Series Chart .swf file instead of Multi-series .swf file and providing multi-series data or vice-versa.

 

I pass in the data via an XML string that executes the following function in FusionCharts.cs. This same XML works when calling the RenderChartHTML method. Any thoughts?

 

private static string RenderChartALL(string chartSWF, string dataUrl, string dataStr, string chartId, string chartWidth, string chartHeight, bool debugMode, bool registerWithJS, bool allowTransparent, string bgColor, string scaleMode, string language)

{

__INIT();

 

// string dataprovider_js_code;

SetConfiguration("debugMode", boolToNum(debugMode));

SetConfiguration("registerWithJS", boolToNum(true));

// setup debug mode js parameter

int debugMode_js_param = boolToNum(debugMode);

// setup register with js js parameter

int registerWithJS_js_param = boolToNum(true);

string dataFormat = GetConfiguration("dataFormat");

dataFormat = (dataFormat == "" ? "xml" + (dataStr == "" ? "url" : "") : dataFormat + (dataStr == "" ? "url" : ""));

 

if (GetConfiguration("renderAt") == "") SetConfiguration("renderAt", chartId + "Div");

 

string wmode = GetConfiguration("wMode");

if (wmode.Trim() == "" || wmode == null)

{

wmode = allowTransparent ? "transparent" : "opaque";

}

 

SetConfiguration("swfUrl", chartSWF);

SetConfiguration("dataFormat", dataFormat);

SetConfiguration("id", chartId);

SetConfiguration("width", chartWidth);

SetConfiguration("height", chartHeight);

SetConfiguration("wMode", wmode);

 

string dataSource = (dataStr == "" ? dataUrl : dataStr.Replace("\n\r", ""));

string dataSourceJSON = "\"dataSource\" : " + (dataFormat == "json" ? dataSource : "\"" + dataSource + "\"");

string chartConfigJSON = "{" + fc_encodeJSON(GetConfigurationGroup("params"), false) + "," + dataSourceJSON + "}";

 

StringBuilder builder = new StringBuilder();

builder.AppendFormat("<!-- START Script Block for Chart {0} -->" + Environment.NewLine, chartId);

builder.AppendFormat("<div id='{0}Div' >" + Environment.NewLine, chartId);

builder.Append("Chart." + Environment.NewLine);

builder.Append("</div>" + Environment.NewLine);

builder.Append("<script type=\"text/javascript\">" + Environment.NewLine);

builder.Append("FusionCharts.debugMode.enabled(true);" + Environment.NewLine);

builder.AppendFormat("var chart_{0} = new FusionCharts({1}).render();", chartId, chartConfigJSON);

builder.Append("</script>" + Environment.NewLine);

builder.AppendFormat("<!-- END Script Block for Chart {0} -->" + Environment.NewLine, chartId);

 

// Re-Initializing...

__fc__initialize__();

 

return builder.ToString();

 

 

}

Hi,

 

To create Pure JS chart please use this code as shown below:

 

FusionCharts.SetRenderer("javascript");

...

Literal1.Text = FusionCharts.RenderChart("../FusionCharts/Column2D.swf", "Data/Data.xml", "", "chart1", "600", "300", false, true);

 

reference: http://www.fusioncharts.com/docs/CS_BasicExample.html#js

 

 

It seems that there might be some issue with your data. Could you please send us the data that is getting created before you pass it to the chart?

I can render the chart no problem with this data if I use the RenderChartHTML function so I can't believe that it is the data. I also only want the chart to render in javascript if no flash is found. I don't want to render in javascript 100% of the time. Is that what your suggestion will do?

Hi,

 

Yes, you are right. The function " _Fallbackjschartwhennoflash()" does not work with RenderChartHTML() method, as of now. We are working on this but unable to commit any timeline on this.

 

Please try using the RenderChart() method to resolve the same.

 

Hope this helps. :)
