DateTimeAxis in Bar Chart not working in 18.4.x

[Jeffrey West]

I can't seem to paste the code here but when I do I get this error...

You have tried to enter a word or URL that is not allowed on this site. If you believe that this is inaccurate, please contact us at [email protected].

So I have attached the code as a file.

When trying to render this page with any build from 18.4.x on I get the following error..

Is this a known issue? If so is there a work around?

Thanks,

Hi Jeffrey,

Greetings from Syncfusion.

We have analyzed your scenario with attached code snippet. By default, x axis supports Double, DateTime, Category, DateTimeCategory and Logarithmic value types and y axis supports only Double and Logarithmic value type. In the snippet, y axis type is specified as DateTime and values passed for y also datetime.

Please revert us if you have any concerns.

This worked in the previous version. Why the change? So now it seems there is no way to have a bar chart with dates on the Y-axis?

Hi Jeffrey,

As stated earlier, we don't have datetime support for y axis from initial for chart control. Please specify in which version your scenario is achieved and kindly share that sample so that we will check the sample from our end and provide an update.
