Stack full graph, not just points

[beibean]

Hi there,

It's my first time using stacked graphs with chartjs and found that it is not working as I expected.

What I can see so far is that graphs are stacked only taking into account the points which share the same X-value, thus if graphs don't share X-value points they are not really stacked on the fully line-graph.

Is this working as expected?

Is there any chance/option to make it work as I described?

Here is a simple repo case:

• https://stackblitz.com/edit/angular-component-x8tbs4?file=src/app/app.component.ts
• Red line → Only have points on X = 0, 1 and 10 which are properly stacked to other graphs.
• Blue line → Points with X shared with red line are properly stacked (sum 1), but other points which don't exists on red line are not stacked with the value of Red line.

Hi, this is the current implementation and there are no options (afaik) that would do what you are requesting.

That said, it would probably not be that hard to implement, because the interpolation functions are already there.

Thank you for the response!

Now I know it's not possible to do it I may think in adding (fake) points to reach the desired graph.
