# Line & Bar Chart
For your chart looks pretty and informative, setting appropriate visualization option is mandatory. In Python mode, we support various options optimized to the **time-series results** from the function codes to help visualizing the charts.
Currently there are two types available for charts in python mode; **line & bar**, **table** You can activate/deactivate each type by using the toggles at the side bar.
***
Once you get to the visualization tab with the python code results, you can see the line & bar is activated by default.

## X-axis
### Value
You can select which column to apply as the X-axis
### Type
You can select the type of X-axis. The options are:
* Time: The X-axis will be a timeline, with each point representing a specific point in time.
* Category: The X-axis will be a list of categories, with each point representing a member of a category.
* Value: The X-axis will be a list of values, with each point representing a specific value.

## Series Setting
### Add Series
Series options are the options that can be set for each series one by one. By adding the series, you can select which column(value) to be visualized.
### Line / Bar select
Line / Bar select button is used to change the **chart type** of the series. If you select `Line`, then the series becomes a line chart. Or if you select `Button`, then the series is shown as a bar chart. Default is `Line`.
### Color
After adding series, you can set the color of series
### Value
You can select Y-axis value of each series.
### Z-index
**Z-index** is used to determine which series is shown over/under another one. The series with the larger z-index will be overlapped over the others with the smaller z-index.
### Y-index
You can choose which Y-axis the series belongs to. The series with the same Y-index will share the same Y-axis. This option is available only when [multiple Y-axis](#multiple-y-axis) option is activated. It can be chosen from 1 to 3.
***
## Common options
Common options are the options that affects the chart and every series.
### Stack
In Python mode, you can choose whether to stack series with same value.
### Multiple Y-axis
Multiple Y-axis is a chart setting that allows you to plot multiple Y-axes on the same chart. This is useful for comparing the values of different variables on the same scale.
### Hide Y-axis
Hide Y-axis is a chart setting that allows you to hide one or more Y-axes on a chart. This is useful for when you only want to focus on a specific variable, or when you want to simplify the chart.
### Line Width
You can adjust the width of the line chart.
### Bar Width
You can adjust the width of the bar chart.
