I understand linear regression is supported in XY and Bubble Charts. Do you anticipate this feature being supported in Line Charts in the future? I know there is a workaround by computing the regression line based on the data points and then using a trend line, but that is a little bit involved. Seems like it would be a good feature.

Thanks for your response. Ward

Hi, do you plan on supporting single series scroll charts in the future? It appears they are all multi series at this time. Also, do you ever anticipate the scroll option to become a standard feature on other chart types instead of having special Scroll charts? I think it would make more sense that way.

So, I guess your answer is no; it's not expected to be supported in the future?

Using a scatter or bubble chart will not work, because in a Line Chart the data points do not technically have a true x-coordinate. The x-coordinate could however be derived from the plotting of the data point once all of the categories are placed. I imagine within the core of FusionCharts you have xy coordinates even for Line Charts.

I really should have explained this better. The x coordinates of the equation would be coming from something like the (total chart width / number of categories) * current count.

Has anyone seen or created a PHP helper to parse through a Rolled Up SQL result while correctly writing the XML data? I'm looking for some sort of function that correctly identifies the NULL (or whatever we name them) values to determine that a new level is required. I'm trying to avoid having to back to MySQL for each level and make it generic enough (recursive) to not have to hard code the number of levels. Thanks for any help offered. Ward

Are there any limitations with linkedCharts and Multi-Series Charts? I can't get this to render (getting the 'FusionCharts' output). Here is some sample XML... <chart showValues='0' bgAlpha='0'> <categories> <category name='Jan' /> <category name='Feb' /> </categories> <dataset seriesname='Plant1'> <set value='113435.705656052' link='newchart-xml-Jan' /> <set value='65744.8482737541' link='newchart-xml-Feb' /> </dataset> <dataset seriesname='Plant2'> <set value='182288.626574397' link='newchart-xml-Jan' /> <set value='99722.7292872667' link='newchart-bxml-Feb' /> </dataset> <linkeddata id="Jan"> <chart> <categories> <category name='Plant1' /> <category name='Plant2' /> </categories> <dataset seriesname='2010-Jan'> <set value='47411.7574198246' /> <set value='95453.3807282448' /> </dataset> </chart> </linkeddata> <linkeddata id="Feb"> <chart> <categories> <category name='Plant1' /> <category name='Plant2' /> </categories> <dataset seriesname='2010-Feb'> <set value='23073.0119767189' /> <set value='43789.7930704355' /> </dataset> </chart> </linkeddata> </chart> Thanks for your help, Ward

Could you instead just point me to your examples for multi-series linkedCharts? Thanks for your continued help!

We'd like to build a linkedChart and then start at a certain level below the top-level. Is there a round about way of trigger drill downs automatically by using the linkeddata id?

Since their links parse hyphens a little differently, you might try to rename your files without them. Shot in the dark, but it might help. Ward

Thanks for your response. 1. Yes, all are included, and I can render other non-linked charts fine. 2. Same as 1 3. No 4. Yes (There would have been an error). I couldn't find any example code for a multi-series linkedChart on your site. If you point me to one, that would help tremendously. Thanks!

Example... -2010 --1Q --2Q --3Q --4Q The xml would contain the parent chart (2010) and the four linkeddata nodes, but we'd like to have the initial view show 3Q. The user would have the choice to click back to return to 2010.

I was never able to successfully reference the internal IDs of the markers and use ajax cluetips; however, I wrote this script which simply shows/hides a div with a XMLHttpRequest call: function map_popup(id, title, worktype, programphase) { openPopup(true, "map_popup"); var element = document.getElementById('map_popup'); var http = new XMLHttpRequest(); var url = "./../requesthandler/request_handler.php"; var params = "title=" + title + "&id=" + id + "&worktype=" + worktype + "&programphase=" + programphase + "&requestType=info"; http.open("POST", url, true); //Send the proper header information along with the request http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", params.length); http.setRequestHeader("Connection", "close"); http.onreadystatechange = function() {//Call a function when the state changes. if(http.readyState == 4 && http.status == 200) { element.innerHTML = http.responseText; } } http.send(params); }

Before switching to FusionMaps, I used an imagemap with an ajax call to dynamically call another page in a cluetip window with the specific location (marker) parameters. I'd like to continue with a similar setup; however, I'm having troubles accessing the XML tags within the setDataXML() method. My attempts so far have been trying to assign a javascript function to the 'link' property of the marker. Do you have any examples that may help me? Thanks, Ward

I think you may have a typo in the first link. It just takes me to the main FusionMaps doc location.

I have been able to successfully use the GUI to generate markers for maps. However, I have some specific maps that need markers bunched together tightly. Changing the map size would make it easier for me to place the markers. Is there a way to change the map size? In FusionMapsGUI.js I have changed the map width and height, but the map size is not changing. Am I missing something? Thanks, Ward

Exactly; however, changing those attributes is not affecting the size of the maps.

Did you open the attachment? The XML is in it.

I understand the use of the GUI. My question is regarding the size of the map shown within the GUI itself. When placing markers, it would be nice to increase the size of the map. That would make it easier to place markers that are close together. I understand the GUI front end doesn't have an option to change the size of the map; however, my attempts to change the underlying code hasn't worked.

Thanks for your continued help to solve this problem of mine. Attached is the full FusionMaps generation statement. jscript_test.txt

This thread gives a hack version of zooming, and I've had some success using it. http://www.fusioncharts.com/forum/Topic10389-11-1.aspx

That won't work, because it looks something like this: setDataXML("<marker id='001' link="j-myJS('blah', 356)" /&gt") No matter which way I order the single and double quotes, there's a conflict with the setDataXML quotes.

Was this feature implemented?

I've been messing around with the Drill Down demo, but I've run into an issue with the string delimiter. Your demo uses an external xml sheet but I need to call setDataXML(). I get 'invalid XML data' for link='JavaScript:myJS("356, blah");' and link="JavaScript:myJS('356, blah');" I've also tried each scenario with the back slash delimiter without any luck.
