I'm getting this error when I try to do a scatter plot using RGraph. I've copied in commons.core etc.: (Sorry - there are no code tags)

<script src='<c:url value="/resources/js/RGraph.common.core.js" />' type="text/javascript" charset="utf-8"></script>
<script src='<c:url value="/resources/js/RGraph.common.tooltips.js" />' type="text/javascript" charset="utf-8"></script>
<script src='<c:url value="/resources/js/RGraph.scatter.js" />' type="text/javascript" charset="utf-8"></script>

This is my canvas area:

<div id='graph-crm-scattergram'>
     <canvas id="scattergram" width="500" height="500">[No canvas support]</canvas>
</div>

And this is my JavaScript code:

normalData = $.parseJSON(str);
var scatter = new RGraph.Scatter('scattergram', normalData);
scatter.Set('chart.tickmarks', 'circle');
scatter.Set('chart.xaxispos', 'center');
scatter.Draw();

I'm just not sure what's going wrong. I seem to have done everything, but something must be missing.

Hi,

That error would suggest that you haven't included the core library. Maybe the path is wrong. Check with view-source in your browser. The tag should look something like this (the path may need changing):

<script src="/resources/js/RGraph.common.core.js" ></script>

I see that you're using single quotes - try changing these to double quotes.

I try to define the chart labels in other language such as

bar.Set('chart.labels', ['&#3617;.&#3588;.', '&#3585;.&#3614;.']);

'&#3617;.&#3588;.' and '&#3585;.&#3614;.' are Thai Language.
But the output seem to be not encoding (look like not UTF-8).

My html file is already set to "UTF-8" charset.
Please advise any solution. Thank you.

Hi there,

By the looks of it you're using HTML entities - canvas is not HTML. So try using the actual characters instead. You may also need to change the pages character set.
