How to set the x axis of chart as numeric value?

[Kang]

Hi, sir

I found the chart node’s X axis is using string type label to display, which will bring two problems below, how can I fix them?

1. The X axis value is sorted by the X array index, not by the X array value itself. Like below:

2. The duplicated X/Y value will not overlap at one point like what we usually do in excel chart, how can I achieve this similar feature like excel chart using chart node?

3. And how can I set the format of X and Y axis, like the major and minor units, label position, XY axis crosses point,etc like what we do in excel chart?

You are more likely to get a helpful reply if instead of a picture of your data, you post some of your actual data.
Maybe 10 data points seems about right.

I believe you are using the original node-red-dashboard.
If I remember correctly, it is only possible with a "stored data" type chart, where you post a batch of x,y coordinates all at once.

Hi, jbudd

If I understand correct, the "stored data" type chart with XY coordinate feature is not available in original node-red-dashboard?

I have to use dashboard2 to have this feature?
