I have a chart setup what I needed to show positive and negative numbers in different colours, how I have achieved this is to check the value before hand and set the topic to High or Low depending on its value. But now I have graphs that look like this. [image] Ideally it would put both lines on…

After a bit more digging and looking at the angular-chartjs documentation for 2.6.0 I see the options used to be under ticks. So I can do what i need to do by using ui= { options: { scales: { xAxes: [{ stacked: true }], yAxes: [{ …

The answer may be somewhere in this thread [image] Stacked Bars Chart with msg.ui_control Dashboard I need to have a bar chart with stacked columns. Unfortunately this is not an option you can find in the configuration window (why?, it's a super standard bar chart style )…

That does get me part way there, I'm still showing 0 values though which I'd like to hide if possible. [image]

What if you set null for values you don't need to show?

I have set them in the config, but since adding the ui_control lines above it is ignoring them [image]

@hotNipi @dceejay Its funny both those code work individually but when I put them together whichever one is on top wins. I'm currently using ui= { options: { "Max": 60, "Min": -140 }, scales: { xAxes: [{ stacked: true …

@dceejay I notice that your the author of that config-fields.md you link me. I've been playing with the interactive bit on this website: Stacked Bar Chart | Chart.js And using const config = { type: 'bar', data: data, options: { plugins: { title: { display: true, t…
