Mixed chart y-axis scaling issue (with stacked true)

[vincemat]

Bug report

Codepen

Please look at this codepen.

Explanation

• What is the behavior you expect:
  I expect the y-axis to be set (near) to the max value (sum of area data or highest value of line data)
• What is happening instead:
  The y-axis is scaled based on the sum of the area + line data which lead to a wrong scaling of the chart
• What error message are you getting:
  No error message, just a question of visualisation of data

I think all 3 need to be area to stack

          type: 'area',

Yes, I understand that the scaling is based on the stacked of the 3 but in my case I would like to have a mixed chart (line+area stacked) without the scaling being the sum of the three but the max(A+C, B)...

[JohnRomanski]

What you are expecting makes sense now, maybe you can add that to the issue description?
In terms of your request, this seems to be an outstanding bug based on #26 (comment)

@vincemat did you find any workaround to solve this issue?
Edit: the only solution for now is to specify max option in yAxis properties

[vincemat]

Indeed, the only solution is to specify a max option in yAxis properties...

Setting a fixed max value doesn't work in all cases, since with it you loose the charts ability to dynamic adjust the Y-axis when a series is hidden via clicking the legend.

So IMHO it would be best to calculate Y-Axis max value like this:

• determine max-value of each data series (i.e. line/area/bar) in the chart
• if type (line/area/bar) is stacked: calculate sum of max-value of all series of the same type
• if type is not stacked: determine max max-value of all series of the same type
• set y-Axis.max to max of all max-values of each series type

best regards

I have the same problem. Has anyone already found a workaround (without loosing the ability to dynamic adjust the Y-axis)?
Issue #531 from 2019 had already described the same behavior.

[vincemat]

I did not find any workaround yet... But I'm totally open to any idea because I'm quite stuck with this...
