The bar chart panel visualization enables you to represent categorical data graphically, specifically when you want to visualize data from a particular field across all the devices in a fleet dashboard.
Add Bar chart panel
Step 1: Select Bar Chart panel from list of panels
Step 2: Choose the data stream and specify the column by which the data should be grouped, such as device ID or firmware version. Next, select the specific data column that you want to visualize.
For example, in this case, we choose the ID value to observe the SOC (State of Charge) value across the devices.
Step 3: By accessing the "View" tab, you have the option to customize the range of the Y-axis according to your preferences.
Step 4: Click on Submit to add the Bar Chart Panel to the Dashboard.
