In the documentation page

http://oxyplot.codeplex.com/wikipage?title=Custom%20trackers&referringTitle=Documentation

it states that you can define what the tracker displays by modifying the TrackerFormatString property of the series. What format is this property expecting? In particular, if I want my tracker to show the following:

X Axis Title: 0.###

Y Axis Title: 0.###

(where 0.### is meant to be the appropriate value to 3 decimal places), what do I have to set TrackerFormatString to? I'm using LineSeries and ScatterSeries, if that makes a difference.

Thanks,

Steve

Sorry the wiki documentation is not finished. 

The tracker format string has some variations for different series (should be documented... and maybe improved?), but it should at least support the following arguments

{0} the title of the series
{1} the title of the x-axis
{2} the x-value
{3} the title of the y-axis
{4} the y-value

For ScatterSeries you also have

{5} the title of the value-axis
{6} the value of the scatter point

This means that in your case you should be able to use

X Axis Title: {2:0.###}
Y Axis Title: {4:0.###}

The format string can also contain names of properties of the items (requires use of the ItemsSource property):

{X:0.###}, {Y:0.###}, {Value:0.###}

where X, Y and Value are properties of your items.

Hello i need help
Ihave a scatterSeries. And i need to for every point's have unique string lines, and this lines must show at the tracker.
How i can do that???

Hello world,

Is there any way to draw simple shapes like circle, ellipse, square, rectangle, etc. on Oxyplot,

without calculating data points for series.

Like in C# there are few direct methods to draw these shapes, is it possible in Oxyplot by directly giving appropriate parameters like radius, center of circle, etc.

Thanks in advance.

objo wrote at 2012-10-03 19:11:

Use 'annotations' to draw content that should not be listed in the 'legend box'. There are implementations for rectangles and lines, but not ellipses. You could derive an "EllipsisAnnotation" in the same way as LineAnnotation - calculate the points and call DrawClippedLine. IRenderContext does not support clipping of ellipses. I did not include clipping in IRenderContext to make it easier to port to different platforms...

Currently I am using OxyPlot to plot vehicle trajectory data. The total number of lines would be around 2000. OxyPlot does a good job to render these lines efficiently and give them a different color automatically.

But I noticed that colors of lines would be changed if I remove one of lines. And it seems like the color would be rearranged by default color order, which is from green, khaki, red...

For example, I plot three vehicle trajectories below.


(https://www.dropbox.com/s/xx2wygeoeg8sg4p/Screenshot_4_26_13_8_10_PM.png)

ID 2270 is in green. ID 2276 is in khaki. ID 2281 is in red. And the order I plot them is start from 2270, then 2276, finally 2281.


(https://www.dropbox.com/s/pw6ptb0a6w1cadp/Screenshot_4_26_13_8_13_PM.png)

Now I remove ID 2276. Then ID 2281's color changed to be khaki from red.

I would like to know if there is a way to keep the line color as it will help user focus on certain line they are working on.

Here lists my code. It's quite simple.

var lineSerie = new LineSeries();

data.ToList().ForEach(d =>lineSerie.Points.Add(new DataPoint(Convert.ToDouble(d.X), Convert.ToDouble(d.Y))));

plotModel.Series.Add(lineSerie);

viewModel.plotModel.RefreshPlot(true);

:)
Thank you guys!

Hello everyone,

I would like to disable the tracker on my plot. Is it possible?

I am using a bar graph, and the default tracker contains the label of each box followed by its value. Another possible option for me is to change the tracker message to have only the box value, without its name. How can it be done?

Thank you.

objo wrote at 2012-07-03 21:05:

I don't think it is possible to hide the tracker. This is related to issue http://oxyplot.codeplex.com/workitem/9625 - it should be possible to change the mouse gesture to activate the tracker - and to disable it. I have not implemented this yet, but hope to do it later this year.

To change the tracker text for the BarSeries/ColumnSeries, try to set TrackerFormatString = "{2}"

I will add more information about the tracker format strings at http://oxyplot.codeplex.com/wikipage?title=Custom%20trackers

FYI, I got around this (what I would consider a limitation) by putting a transparent Border (or Rectangle would also work) over the chart to prevent mouse events from getting through.
