HorizontalBarChart bars do not render if all input values are under 10

[mcooke-mdkl]

I had an issue with the HorizontalBarChart, where all of the values were under 10. This caused none of the bars to render.

Context:
I wanted to display all orders per hour over a 24 hour period.
InputData="0,0,0,0,0,0,0,0,0,0,0,1,0,2,1,1,7,0,0,0,0,0,0,0"

As none of the values were over 10, it had the effect that none of the horizontal bars would render.

I fixed it with the following change to the HorizontalBarCharts.cs

//Check the highest value in inputDataArr, if below 10, set the gridYUnits and gridXUnits to 1
var units = (inputDataArrDouble.Length > 0 && inputDataArrDouble.Max() < 10) ? 1 : 10;

double gridYUnits = units; //old value was hardcode to 10
double gridXUnits = units; //old value was hardcode to 10

It works fine for my needs.

Thanks for creating these charts. They are simple and easy to use.
