Custom callouts on RadHtmlChart

[Ted]

Is it possible to have a custom callout on a RadHtmlChart?  (See attached - "Mailer Sent" and "Website Launched")  The chart has three line series within it, using a date along the x-axis.  I tried adding a scatter series to put an individual point on the chart, but when I specified a date for the XValue, it gave me an error (problem converting to integer)

Is this possible?  Is it a matter of mixing two different types of charts?  (lineseries and scatter)  How can I best accomplish this?

Thanks!

Hi Ted,

LineSeries uses a categorical XAxis, while the ScatterSeries and ScatterLineSeries use a numerical XAxis. The RadHtmlChart does not let you mix a Series of different types. You can have a look at this online demo related to mixing chart Series.

Regarding the callouts, RadHtmlChart does not support such functionality. You can, however, achieve that effect by creating and aligning styled div/span elements that contain the desired text over the desired area from the RadHtmlChart. There is a good example on the KendoUI's Bubble chart demo, that show how to create a legend manually through such styled div element.

All the best,
