Hi. I am looking for an example of using a legend item template with checkboxes to show/hide the different series. could not find one any help will be appreciated

Hi there. I'm still having many problems with this approach. My span can vary berween day, week , month etc... When the span is day it look great, but on other variants, setting the step to be the XWidth of the bar to be the span (week = 7 days, month = 30 days) it looks wrong, the bars and the step don't match, the labels appear not on the ticks as it should and it just not working. I am still not sure why doing what i did with the string labels (persuming i make sure all the dates are consecutive and if there is a gap i make sure to fill it with a zero value point)

This method didn't work for me. I have tried a different approach - I have added a label property for my clr object, and set the label binding path to this property. however now i don't see any labels at all as before when i set the labels binding path to the 'X' property, I saw the labels but they were not formatted and only shown the date part of the the date time. What am i missing ? I was sure this would work as I simply assign a different property of string type to the axis x labels.

Hi. I am creating a bar chart using this code : SeriesAttributes sa = new SeriesAttributes(); sa.BindingPath = "Y"; _myChart.AxisX.Labels.BindingPath = "X"; The item source is a clr object collection where the clr object has two properties - x (datetime) and y (double). The problem i am having that the labels on the x axis are always appear as dd MMM yy even when i change the _myChart.AxisX.Labels.CustomFormat to something different - this works fine when doing the same for a line chart, but not on a bar chart.

Solved. this settings is what was needed ,and it will help us later when we need to export chart w/o it ever being loaded so I will use the RendedBeforeLoad settings. Thank you.

for any wpf control, the code for export a visual to image works, however for your chart element , it does not. doing the solution with the thread first gave me the cross thread violation , and using the dispatcher invoke, the result was that the image was not even black - it was completely empty. Can you think of another path for solving this critical issue ?

Hello there. In my application I have multiple chart elements in different tabs. one scenario demands me to export all currently opened charts to images. however doing so results in black empty images for all charts that are not currently visible to the eye (visibility is visible but they are in a tab that is not the current active tab). Can you think of a reason a chart will export to a blank image ? Do you need more information on this issue ?

Hello there. another issue i'm having with mouse interaction , is working with two chart elements on the same container. I need two chart elements (not two panes but two instances of the chart object) that will both be interactive. when i set mouse selection on the first chart and then on the second , IT will not be available on the second chart. I need an option to zoom on the 1st chart, and while viewing it zoomed , start a mouse selection on the other one. Is this possible ?

One thing I have noticed, is that if a mouse selection has started, any mouse interaction like tool-tips, moving the scroll-bars when zoomed is disabled. I find this behavior limiting since I'm trying to achieve continous zooming (select a zoom area, and on the scroll view changed start another zoom selection so i won't need to click on a button to start each zoom selection). when this is the case, I cannot interact with the scroll-bars.

You can discard the last question - solved this it was in my code after all.

Hi there. I have noticed that if i select an empty area (no markers), the continuous selection will not work. something is changing the zoom mode to off or something. I could not trace it as it happens in your dll code. Could you check this also and provide a hot-fix if possible ?

My bad. i didn't remove the old refernce so the files in the bin were the old ones. The hotfix did the job. good work !

another issue i'm having is being able to cancel the mouse selection operation once started. In my application i need the option to click on a button and the mouse selection will be canceled.

That doesn't give me the ability to change some of the points - i.e change all points marker above a certain spec value or change marker of every 5th point ... is this even possible ?

I installed the hotfix but this didnt solve my problem - the second time I call the start mouse selection (on the databound event) it doesn't work.
