# Creating a .NET MAUI Range Column Chart to Compare Average Temperatures in Rome
2+
A range column chart is a valuable tool for visualizing data intervals, enabling comparisons between categories or time periods. It's particularly useful for showing variations and trends in data sets with upper and lower values.
3+
24
This sample demonstrates how to create a Range Column Chart to compare average temperatures in Rome using .NET MAUI (SfCartesianChart).

### Customizing Chart Appearance
9+
We can customize the chart appearance by the following ways:
10+
11+
#### Customizing Range Column Series Placement
12+
We can customize the Cartesian chart by choosing whether the Range Column series should be placed side by side or overlapped.
13+
14+
#### Adding a chart title
15+
A chart title provides essential context to the plotted data
16+
17+
#### Chart Axis Customization
18+
We can further customize axis elements, including axis label style, axis label placement, and adjusting the axis range.
19+
20+
#### Chart series Customization
21+
We can customize the chart series by applying the desired series color, and enabling or customizing data labels for each series in the chart.
22+
23+
#### Chart Legend Customization
24+
The legend provides information about the data point displayed in the chart.
