Disabling padding does not work for empty plots (WinForms)

Describe the Issue: I use it as the initial Form. I can’t achieve my goal without data. Like this: Without data: The LightBlue is the padding that I want to eliminate. But I can eliminate it by adding the data. Like this: With data: This is my code and it is the demo about Customize: Figure - No Padding.

var plt = this.scottPlot.plt;
plt.PlotHLine(2);
plt.Style(figBg: Color.LightBlue);
plt.Style(dataBg: Color.LightYellow);
plt.Ticks(false, false);
plt.Frame(false);
plt.TightenLayout(padding: 0);
scottPlot.Configure(recalculateLayoutOnMouseUp: false);
scottPlot.Render();

How can I eliminate the padding except by Adding data?

Further debugging，I find an amazing phenomenon. I remove the part of your code. So I can’t get my goal.

Before modification

		private ScottPlot.FormsPlot formsPlot1 = new ScottPlot.FormsPlot(new ScottPlot.Plot(200, 200));
		private ScottPlot.FormsPlot formsPlot2 = new ScottPlot.FormsPlot(new ScottPlot.Plot(200, 200));

After modification

		private ScottPlot.FormsPlot formsPlot1 = new ScottPlot.FormsPlot();
		private ScottPlot.FormsPlot formsPlot2 = new ScottPlot.FormsPlot(new ScottPlot.Plot(200, 200));

The result

Automatic generated by Visio studio

		this.formsPlot1 = new ScottPlot.FormsPlot();

I think it is my Heart of the matter. I add the code and get goals successfully.

Hi @YUXI07, thanks for the question and @bclehmann for your help along the way!

To summarize the problem, plots weren’t rendering framelessly in the FormsPlot control if they were empty, and that this is an an issue that only applies to version 4.0.

The fix is to instantiate the FormsPlot control by passing-in a new Plot with a defined size, rather than letting it create one.

I too am puzzled by this solution, but am happy to hear @YUXI07 ended-up with something that gets the job done! 👍
