For an internal company application I want to visualize bank account balances over time.
The natural way to do so is via a line graph but a line graph automatically draws a line between the different data points. I need the line to be flat between the different data points to reflect the actual account balance.
Example: If the account balance is 8M EUR at 10:00 and 10M EUR at 12:00, it is not true that the account balance is 9M EUR at 11:00, which is the way Tableau draws the line.
Is there way to change the way the line graph as shown in the attached image? I want to achieve the effect of the dotted black lines instead of orange lines.
