Indicators problem

[Flash]

Hi

Can you explain me why indicators gon't display from beginning of the axis? Look like they miss first pack of data.

You can see this in you telerik demo application if you zoom axis (chart->chart types->indicators)

Is it a way indicators works or trial version limitation?

My problem that i have about 30 points for chart and can't see indicators at all.

Hello,

Thank you for writing.
The reason for this behavior is because the indicator values are calculated based on previous periods of time and the first points are used to calculate the first value of the indicator. That is why it doesn't start from the beginning of the data set. You can solve this by changing the minimum range of the x axis:

xAxis.range.minimum = min;

Another option is to manually create the x axis specifying appropriate minimum and maximum:

TKChartDateTimeAxis *xAxis = [[TKChartDateTimeAxis alloc] initWithMinimumDate:[NSDate dateWithTimeInterval:60*60*24*7 sinceDate:minDate] andMaximumDate:maxDate];

I hope this helps.

Hi, I am having the same problem. For the MACD this is the proper behavior for an indicator:

It uses previous points to calculate the present point. So I am not clear on why the Telerik indicator behaves this way.
