Chart With Multiple BackColours c#

Question

I'm looking to fill a c# chart with multiple backcolours in relation to timestamp.

Does anyone know of any code to do this or perhaps a method to implement the equivalent.

I thought about adding semi-transparent columns with appropriate widths but this seems a bit messy.

Any insight and ideas would be appreciated.

This sound like a jobe for [StripLines](https://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.stripline%28v=vs.110%29.aspx). See [here for an example](http://stackoverflow.com/questions/38958646/winforms-chart-how-to-enable-background-color-gauge/38959173#38959173) — TaW, Aug 28 '16 at 19:05

If you are using mschart

Use a timer
Every tick event, set back color to color you want

thanks for the reply, but will that change the entire background colour of the chart per tick or will it colour it in periods so you get a progressive colour change? – Mark Corrigan Apr 18 '14 at 09:09
yes, it will change the whole background color every tick. – jhyap Apr 18 '14 at 09:45
sorry, to be more specific the application requires a progressive of colour with time thus when viewing historic data a chart will appear to have a different colour depending on time of day. It's to represent RAG times used in power distribution – Mark Corrigan Apr 27 '14 at 18:55

It would be helpful if you can picture your idea inside your question to help us understand the problem better. – jhyap Apr 28 '14 at 00:26

                point.Label = string.Format("{0:0} - {1}", point.YValues[0], point.AxisLabel);
            }
