Hi Bart,

In Odoo studio, not all field types are suitable for display in a graph view. Generally, fields that contain numerical or quantitative data are more suitable for graph views, as they can be visualized effectively using graphs such as bar charts, line charts, or pie charts.

Here are some common field types that are typically suitable for display in a graph view:

1. Integer fields: These fields store whole numbers and are commonly used for counting or numerical data.
2. Float fields: These fields store decimal numbers and are useful for representing quantities or measurements.
3. Monetary fields: These fields store currency values and can be visualized in graphs to represent financial data.
4. Date and DateTime fields: These fields store dates and times, which can be used to analyze trends over time in graph views.
5. Selection fields: These fields offer a predefined set of options and can be used to categorize data for visualization in graphs.
6. Many2one and One2many fields: While these fields themselves may not be suitable for direct visualization in graph views, they can be used to establish relationships between records that are then visualized using related fields.

It's important to note that certain field types, such as Text or Binary fields, may not be suitable for direct visualization in graph views due to their nature. However, they can still be used in conjunction with other fields to provide context or additional information in the graph view.

In summary, while not all field types may be directly suitable for display in a graph view, Odoo provides flexibility to create meaningful visualizations by leveraging appropriate field types and relationships between data.
