Is this a bug? Spline Chart & Graph

[Zydenhx]

Hi,

Been testing out the spline chart earlier, but there seems to be a problem when trying to plot the chart with an Empty or null data points. The graph will curve and bend in a weird ways, by default it should be only have an empty gap between non empty data points plotted in the graph. Is there a possible solution for this?

I have attached the image example below for more clear describe of the situation.

The dataset used as an example: 

Jan: 123, Feb: 124, Mar: 123, Apr: 124, May: 123, Jun: empty, July:  empty, Aug: 124, Sep: 123, Oct, 124, Nov: 123, Dec: 124;

I'm looking forward to any reply, thank you.

Hi Durga, 

I figured out it happened when having two series plotted on the same chart and both series have different x axis value. Is it possible to just plot the chart with the most x axis value data? (in the case of the example would be all months including  Jun and July.

Here's an example of the replicated issue: https://stackblitz.com/edit/wt8izv-6xras1

You can see "Jun and July" on the x-axis placed after "Dec" because the first dataset does not have "Jun and July" while the second dataset have  "Jun and July". if first swap both of the dataset it will plot like the image attached.

Hi Durga,

Apparently, after I updated to the latest version, the bug is still there. Might be the cause of this warning that I attached in this reply.  May I know how to solve this issue?
