One more question, is it possible to click on a chart and know where the click occured?  I want to zoom based on a list of durations i have.  I want to click and zoom to the next shortest duration in my list, however i would like to do this and center to where the click occured.

Example,

I am zoomed into an hour time frame between 1 and 2 oclock.  i click on the xamdatachart, my next shorter duration is 30 minutes.  If i would click directly on 1:30 i would want my 30 minute duration to show from 1:15 to 1:45.

Hello, 

Thank you for posting. 

I have been looking into your questions and I could suggest you the following:

1. The size of the zoombar thumb could be change using the MouseDown event and moving the pointer. This could be disabled by adding an event handler for the MouseDown event. In the attached project  the default HorizontalScaleLeftStyle and HorizontalScaleRightStyle are used to add the handlers and mark the MouseDown event as handled: e.Handled = true;
2. To use the arrow keys for changing the position of the zoombar thumb you could add handler of the KeyDown event of the window/container where the zoombar is positioned. Then check if left or right key is pressed and change the Maximum and Minimum properties of the zoombar range. In the sample project the range of the thumb is 10 and the SmallChange property is set to 10. This is the reason why Range.Maximum and Range.Minimum properties are changed with this value.
3. About your third question I am not sure what you are trying to achieve. What do you mean by “my next shorter duration is 30 minutes”? How do you change the time frame?

Please note that it is always better to post in separate forum threads the questions that are not closely related as it is easier for the community members to find the information they are looking for. Thank you.

I am changing the time frame using a drop down. my dropdown for example contains " 1 hour" and "30 minutes". If iwas showing the hour between 1pm and 2pm on my chart.I would like to click directly on 1:30 and have my 30 minute duration to show from 1:15 to 1:45. So the graph would now show 30mintes of data because the click event would trigger the chart to use the next shortest duration in my list. it would also  register where the click occured, that exact time on the chart  would be the middle of the 30 minutes i would show.

Hello Pete, 

I have been looking into your scenario and it currently this functionality is not available with XamZoombar. SmallChange and LargeChange properties could be set in order to control the steps the thumb is moved. Please note that the thumb has defined width and it is not possible to place it at a random position where the user had clicked. When user clicks on the bar the thumb is moved using the LargeChange step. If the thumb should be places precisely, the user could drag and drop the thumb at particular position.  

how can i get the location of a click on the zoombar and move my zoom to that position, keeping it in sync with the datacharts.  I need to be able to click on a spot on the preview data chart in my zoombar and have the slider move there and also have the datachart above show the correct information

This has all worked wonderfully, however i now have another related issue.  I am capturing the mouse down event so that the user can not resize the thumb slider by clicking on the horizontal scale part of the thumb slider.  I need to have the user be able to grab and slide the thumb when it is zoomed into a level where the user can not grab the slider. See attached document*

Thank you for your feedback Pete. I am glad that everything is working as you need now. I believe that this might be helpful for other users, too.
