Can "jsk_rviz_plugin/PieChart' change rotation direction?

[fuhuan26]

Hi,
The default rotation direction for pie chart is counterclockwise. I am wondering if there is a way to change it to clockwise.
As I would like to use it to mimic vehicle speedometer, which is more intuitive in clockwise.

Thanks!

this is because we develop this plugin for decreasing values such as battery capacity or voltage.
but I think it is good to add new option like rotate direction for this rviz plugin.
We welcome for your contribution, and we look forward to seeing a PR for the new feature.

Thank you for your reply, @knorth55. Could you please point me which file is for the current piechart implementation? I am happy to take a look and work on adding the direction selection feature. Thanks!

@fuhuan26 how about this option #782 ?

@knorth55 That looks great! Really appreciate your prompt help! One last question, I installed the package using sudo apt install ros-melodic-jsk-rviz-plugins And I was not able to locate the pie_chart_display.cpp file and apply the change.

Can you please show me where to find that file and then how to recompile the package? :)

Thanks a lot!

@fuhuan26 You can install jsk_rviz_plugins from source:

cd /path/to/your/catkin_ws/src  # In the following, I use "catkin build" command. If you have a workspace using "catkin build", you can use that workspace. If you have a workspace using "catkin_make" and don't mind building time, you can use that workspace on condition that you use "catkin_make" instead of "catkin build". If you don't have a workspace, please create it by "mkdir -p /path/to/your/catkin_ws/src" and I recommend using "catkin build" in the following.
git clone https://github.com/knorth55/jsk_visualization.git
cd jsk_visualization
git checkout pie-chart-clockwise
cd /path/to/your/catkin_ws
rosdep update
rosdep install --from-paths src --ignore-src
sudo apt install python-catkin-tools  # If you use "catkin build" for the first time
catkin build jsk_rviz_plugins  # or just "catkin_make" if you choose to use "catkin_make"
source /path/to/your/catkin_ws/devel/setup.bash  # This is required on every terminal launching rviz
