If you want to focus on a specific part of your dataset, Flourish enables you to adjust the minimum and maximum of your visualization's axes and create a custom range.
To adjust the range of your axes:
X axis
Date data
When the X axis features date data, head over to the X axis settings, and enter the minimum and maximum date ranges you want in the Min (date) and Max (date) fields, respectively.
Warning: The date format you enter must be the same as the date input format in the datasheet. A primer on date formatting and how to change it can be found here.
Numerical (non-date) data
When the X axis features non-date numerical values, the settings are slightly different. Scale options are available, that enable you to choose between a linear and a logarithmic scale and also to set custom minimum and maximum X axis values.
Y axis
For a custom range on the Y axis, head to the Y axis settings and input the values you want in the Min and Max settings.
