Hello

I have an array with 2 datasets in it which I inject into a chart. One set is the x-axis labels and the other is y-axis values.

I have the series colour in the chart set to blue and ticked the box " Use first colour for all bars ". However, one of the bars I'd like to make a different colour.

Is this possible? Can you specify individual bars to be individual colours?

Yes it is possible, you would need to create two lots of the data,  
eg  
0,0,3,0  
2,4,0,2  
OG data 2,4,3,2  
And then stack the bar chart  
Not knowing what dashboard you are using
