Multi-series spline Issue

[jtr]

I am having issues getting a multi-series spline chart working. I can do it when hard coding the data arrays but am using json data.
I have it working just fine with a single series but it bombs when I add the second data series. My syntax must be off somewhere but I think I have followed it correctly. I am newbie to this forum and to canvasjs. Any help would be welcomed. I am happy to sare the code.
I am using the php echo json_encode in the databapoints; section

@jtr,

Please take a look at this Gallery Page for an example on rendering chart with data from JSON in PHP. If you are still facing issue, kindly create a sample project reproducing the issue you are facing & share it with us so that we can look into the code, understand the scenario better and help you out.

I finally worked it out.
It was because the title variable from php changed from text to number during a looping increment (for year). The canvasjs does not accept numerics as title objects it would seem. All I had to do in the end was to strval() the title variable before doing the json_encode.

@jtr,

Glad that you figured it out :)
