Normalising data and Actual data for Tooltip

AndyC1000 asked
Last Modified: 2012-05-10

Working on normalising data to plot on MSChartControls Radar chart.

Found an example -
a+ (X-A)(b-a)/(B-A)

A - Min of your dataset
B - Max of your dataset
a - Min of normalised dataset
b - Max of normalised dataset
X - the value

I need to also keep track of the actual values what will appear on a tooltip.  

Currently this is how I populate the radar chart with the actual values -

for (int i = 0; i < seriesArray.Length; i++)
System.Windows.Forms.DataVisualization.Charting.Series series =
new System.Windows.Forms.DataVisualization.Charting.Series();
series.ChartArea = "Default";
series.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Radar;
if (colourIndex >= colours.Length)
colourIndex = 0;
series.Color = colours[colourIndex++];
series.Legend = "Default";
series.Name = "Series" + i;
series.ShadowOffset = 1;
series["RadarDrawingStyle"] = "Line"; // Radar chart style (Area, Line or Marker)
series["AreaDrawingStyle"] = "Circle"; // Circular area drawing style (Circle)
series["CircularLabelsStyle"] = "Horizontal"; // Labels style (Auto, Horizontal, Circular or Radial)

for (int j = 0; j < labels.Length; j++ )
string l = labels[j];
series.Points.DataBindXY(labels, seriesArray[i]);

Open in new window

I'm not sure about the best way to keep track of both these datasets.

Thanks, AC
