  1. Chrome Refuses Exportchart()

    Yes, they are in the same domain. I solved the problem by removing the Javascript command to set the charts' container div's CSS to have position: fixed. I seems that this causes the Flash object to be erased temporarily and then re-instated after the container div has been moved to the fixed-position space in the browser window. So to have the fixed position (thereby allowing the chart to scan the bitmap for export no matter where the user scrolls to) AND actually export, I had to load all the charts, position them, wait for 1000ms, and THEN call exportChart() on all of the charts. That way works great.

    Actually now even with the delay it refuses to export anything in Chrome. Maybe the delay does not help after all. How do I make the SWF call FCExporter like it does in all the other browsers?

    Here is the same sample with the delay added: for (var chartId in FusionCharts.items){ var curChart = getChartFromId(chartId); if (curChart.hasRendered()){ window.setTimeout(function(){ curChart.exportChart(); }, 5000); } } Why do you suppose the SWF objects need this delay before calling their Javascript exportCharts() hook will do anything? Maybe they javascript and html are done rendering and being defined before the SWF objects finish loading?

    Adding a delay makes it work in Chrome...but unreliably.
  6. Chrome Refuses Exportchart()

    It's starting to look like the SWF files are the ones that try to execute the FCExporter.php script. Or rather in this case, they don't try. How do I fix that, if that's the case?

    Further investigation reveals that FCExporter.php is never executing.
  8. Chrome Refuses Exportchart()

    I have debugged and dug in a little deeper. I have found that for (var chartId in FusionCharts.items){ var curChart = getChartFromId(chartId); if (curChart.hasRendered()){ curChart.exportChart(); } } just loops through and never exports any charts in Chrome, but works great in all other browsers.

    Correction: I just put console.log() calls immediately before and after the failing exportChart() call. Both console.logs execute successfully. However, the chart does not start the bitmap scanning process to create the image file. It will in other browsers, just not in Chrome. Do I need to insert a small delay before calling exportChart to have it scan the image out to a file in Chrome?
  10. Chrome Refuses Exportchart()

    Thank you for the slick example. Unfortunately I miscommunicated what I need. My code successfully clones an exportable flash chart, after starting with a HTML/JS/SVG chart on the page. That's what I want. But the part that isn't working (only in Google Chrome, no other browsers have this problem) is when the method exportChart() is called by my script. When the code hits that point (and I've debugged step by step to ensure this is the spot it fails at), then the javascript simply halts with no error. It's as if the exportChart method doesn't exist on the clone. The strange thing is that I can trigger this exportChart() method from the Google Chrome console. Why won't it let my script see the method, but it lets it see all other methods (except for maybe hasRendered or isActive?) All other browsers can see these methods on the JS objects that correspond to the flash charts on the page. Aaron McC
  11. Rendering Problems

    If you need different sizes for different screens, you can test browser window viewport size and add size params before rendering chart, depending on the process you're using to bring charts onto the page.
  12. Bgalpha Broken In Ie

    I wonder if it's trying to use hex or RGBA color style in CSS to do this... If it's not a flash chart, it might be. In that case, not surprising if it uses CSS. If it uses CSS then it can't do alpha in IE without the filter: Alpha style rule. Just speculation, but maybe that's a place to start.
  13. Chrome Refuses Exportchart()

    Thank you for testing it on your system. I must be doing something in my javascript that is preventing the export() function call somehow. Perhaps the inclusion of another Javascript library is interfering. At least I know that it should be working in chrome, even on a cloned Flash chart. That helps narrow down the problem a bit. I would like to receive your demo at [email protected] By comparing our code I may be able to find the flaw in mine.
  14. Chrome Refuses Exportchart()

    Thank you. I included doneSavingChart() just so the rest would make more sense. During the problem though, since no exports happen, the callback doneSavingChart never happens either. There is a lot that goes into all this across multiple files, so for you to be able to test it I'd have to put quite some time into developing a reduced test case. I hope you can ascertain some flaw that is Chrome-specific by just reviewing the code. I would like to include the chart HTML but it contains company information that I probably don't have permission to divulge. I'm sorry that's not very helpful. If reviewing the code gives nothing significant to pursue as a possible solution, I'll see what else I can arrange for you. Keep in mind it's specifically a Chrome issue. Testing in Firefox, IE, and Safari this problem does not occur. Have not tested in Opera yet. //callback for when a chart finishes saving to server disk. This was set up in dashboard_body.php function doneSavingChart(objRtn){ var domID = objRtn.DOMId; var fileName = objRtn.fileName; //window.setTimeout(function(){ numChartsSaved++; var fileNameContainerId = 'chartFileName---' + domID; $('#' + fileNameContainerId).text(fileName); var chartDiv = $('#' + domID).closest('.frame').find('div'); //$(chartDiv).css({left:'', top:'', bottom:'0', right:'0'}); //busyChart = null;//clear it here to start another chart exporting when the current one is finished. if (numChartsSaved < numChartsToSave){ return; }else{ window.clearInterval(exportProcessTimer); var dataObj = new Object(); dataObj.sectionLabel = $('#menu li.current').text().replace(trimPattern, ''); dataObj.dateRange = fetchDateRange(); dataObj.chartData = fetchChartData(); postReport(dataObj); } //}, 500);//small delay to make sure the picture has finished saving. } //timed polling function to take next action in report/export process: function exportCharts(){ busyChart = null;//clear busyChart here if you want it to start another export every time the exportcharts timer fires. clear it in doneSavingChart to start another one every time a chart completely finishes exporting. //I am putting this delay in between calling somechart.exportChart() because I have observed it prevents blank image exports (otherwise file handle getting yanked before it can write? It was not designed for bath exporting after all). if (numFlashChartsMade < numChartsToSave){ //$('.ui-jqgrid-titlebar-close').click();//open them back up. Probably not important for FusionChart export, but this way I can see everything non-chart that we'll be putting in the PDF. for (var chartId in FusionCharts.items){ var curChart = getChartFromId(chartId); if (curChart.hasGeneratedExportCharts || curChart.isExportChart){ continue;//don't generate exportable charts from already-exportable charts.

  15. Chrome Refuses Exportchart()

    All browsers except Chrome will execute the call to someChartObject.exportChart(); There is no error, it just does nothing at that line of code and continues on with the rest of the script perfectly. Maybe it's getting a different object than the other browsers, an object that doesn't have that method? I get the charts in a loop: for (chartId in FusionCharts.items) and inside the loop: var curChart = getChartFromId(chartId); and then inside the loop I call: curChart.exportChart(); Every line of code executes except for that one. It's as if it's commented out. P.S. Maybe it's executing and just deciding to do nothing?
