Hello good afternoon.

I ask for your support, for the following.

In a graph, when there are many elements in X, the labels come together a lot and the text is not understood.

When I apply a configuration by code, the graph does look better:

            horizontalAxis.MajorTickInterval = 10;
            horizontalAxis.TickLength = 10;
            horizontalAxis.TickWidth = 10;

I am using a RadChartView to display a bar chart with a vertical linear axis. I adjust the values in the bars such that sometimes the plotted range in between 0 - 99 (so the axis tick labels have two digits), and sometimes the plotted range is between 100 - 999 (so the axis labels have three digits).

When the maximum number of digits in the tick labels changes, the horizontal position of the Y axis is adjusted to accommodate the increased label size.

Presumably this problem would also arise if the font size of the labels is adjusted.

Is it possible to disable this behavior and allocate a specified "margin" size in which to place the axis labels? I would like the position of the vertical axis to be fixed within the control's area.

Hi,

I'm trying to create a specific chart in RadChartView, where I need to have some annotations which are outside the grid area.  I thought I could extend the axis beyond what is needed and then add the annotations in the space created.   The chart will always have a minimum value of 0, so I extended the axis to -20, which works well to create the space.

However, to make it look correct I need to be able to override the rendering of the axis line, label and grid lines in order to remove the labels for negative values on the axis, and remove the grid and axis lines so the negative space doesn't appear to be part of the chart.  I've managed to do this for the labels, but cannot find an example of overriding the generation of the grid lines or axis line.

Attached is an image of where I am currently at - what I need is to remove all lines on the grid below 0 on the vertical axis.

Has anyone got an example of doing this, or something similar?

Thanks,
Neil.

I have a ScatterSeries  within a RadChartView which is bound to a BindingList of x-y plot points.

When the BindingList updates, the points on the chart are re-plotted , but are being plotted in the middle of the chart, with a large amount of whitespace between the extreme values and the bounds of the chart. The Maximum and Minimum axes values are seemingly decided automatically and at random (if there is some logic to amount of the whitespace being applied, I cannot discern it).

I would like the leftmost plot ploint to be flush with the leftmost axis, the right most plot point to beflush with the right axis, etc. (i.e. I want the axes to be "tight" around the data).

I can do this manually for a known data set with the following code:

LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
// or verticalAxis = series.VerticalAxis as LinearAxis;
horizontalAxis.Minimum = 1;
horizontalAxis.Maximum = 7;

Is there a way I can apply this to ensure that the axes are flush with the outermost data points every time the chart is updated due to the binding? Is there a way  to do this without manually setting values for the axes Maximum and Minimum?

I tried applying the following setting to the axis but it does not seem to produce the desired effect; there is still whitespace between the plotted data and the left and right borders of the plot.

horizontal.RangeExtendDirection = NumericalAxisRangeExtendDirection.None;

We are attempting to make use of ChartView to plot a large number of data points, which display live data which is being received one point at a time. We are experiencing poor performance, with the charts rendering extremely slowly and presence of the resultant chart causing the application performance to drastically deteriorate, (presumably because of the large number of graphical elements present on screen).

We are attempting to implement a LineSeries (or FastLineSeries) which can display up to 90,000 data points.

Is there any guidance available regarding the capability of ChartView to plot a large number of points? Is plotting this many points something ChartView is capable of?

I believe that Telerik UI for WPF contains functionality to reduce the number of plotted points using sampling. Is there similar functionality available for Telerik UI for WinForms? Can you suggest an approach to implement similar functionality in a WinForms application?

For our requirements, one point is added to our dataset at a time; the remainder of the dataset remains fixed. Presumably, the entire chart is redrawn each time a new point is added, which is computationally expensive. Is there any way we can improve the chart rendering performance by removing the need to redraw the entire chart, adding only the novel data points to a pre-existing drawn series?

Are there performance considerations one should take into account when deciding whether to take  a data-binding-based approach or to directly add the DataPoints?

Hello good day.

I am making an application that shows a graph, I use the chartview control, but when there is too much data on the X axis, the information is not distinguished.

I have read that it can be fixed by using MajorTickInterval on the horizontalAxis, I use this lines:

horizontalAxis.LabelFitMode = AxisLabelFitMode.Rotate;
horizontalAxis.MajorTickInterval = 7;

The clearest information is already displayed, but when displaying the information some data should appear in the graph but they are not shown because they are not in the interval.

Is there a solution?

Another question,

Can you remove or hide from the graph the values that have zero or null on the X axis?

Awaiting your comments.
Thank you very much.

Hi.

I'm trying to draw a specific graph using RadChartView.

However, I couldn't find a way to remove the border line, which is marked with a red arrow in the attached image.

The background color must be Transparent.

Please tell me how to remove only those lines.

I use Telerik.WinControls.UI.RadChartView

I try to use RadChartView for show graphical lines. I have prepared series of ScatterLineSeries and upload its to RadChartView.Series. First page can show successfully. Unfortunately I can not show next page. I setting break after uploading data to RadChartView. Visual Studio mark by red color any changes (differences) in RadChartView properties and data.

I can see only small changes in data value and no more.

So, data for showing on second page is similar to data on the first page. However RadChartView show absolutely empty page.

Can anybody advice for me, what checklist I can pass to understand why second page is clear blank page?

Hi 

I would like to create charts programmatically  and display them in a table of two columns (like the attached photo) and and be able to drag and drop the displayed charts to change their locations. Is there a way to do this using the UI components for WinForms?
