Hello Ramya,

Thank you for contacting us.

You can give custom color to TKChartLineSeries by adding a custom TKChartPaletteItem to the palette property of TKChartLineSeries.

TKChartLineSeries* seriesForIncomes = [[TKChartLineSeries alloc] initWithItems:pointsWithCategoriesAndValues];
seriesForIncomes.style.palette = [[TKChartPalette alloc] init];
TKChartPaletteItem *item = [[TKChartPaletteItem alloc] init];
item.stroke = [TKStroke strokeWithColor:[UIColor purpleColor]];
[seriesForIncomes.style.palette addPaletteItem:item];

Yes, there is a way to set different color for every datapoint in your chart. You should adopt TKChartDelegate protocol and implement its chart:paletteItemForPoint:inSeries:  method. 

-(TKChartPaletteItem *)chart:(TKChart *)chart paletteItemForPoint:(NSUInteger)index inSeries:(TKChartSeries *)series{
    NSArray *colors = [NSArray arrayWithObjects:[UIColor blackColor], [UIColor greenColor], [UIColor redColor], [UIColor orangeColor], [UIColor yellowColor], [UIColor brownColor], nil];
    TKChartPaletteItem *item = [[TKChartPaletteItem alloc] init];
    item.fill = [TKSolidFill solidFillWithColor:[colors objectAtIndex:index]];
    return item;
}

I hope this helps.

We do not provide VB.NET code samples but you could use a online converter to do the conversion.
