This page brings together a number of special charts, or chart options, with a high level of customisation:

• grid / zone (XY chart and ternary diagram)
• normalisation (Y chart – spider diagram)
• geological time scale (among others)

In view of the level of customisation, each of its graphics includes lists of options that are pre-integrated, but can be modified at will by users. If you feel that any of the classics are missing from these lists, please don’t hesitate to contact me.

Grid/zone integrated into a chart :

This option lets you display/add custom grids/zones to graphs so that you can represent data on a defined diagram. This option is available for XY and ternary charts.

The list of grids already included in Better Plot is available here, with many thanks to the GeoPlotter website and its creator, from whom the majority of the grids come.

How to use it :

When the “XY – grid graphic(s)” and “Ternary diagram” chart types are selected, a new section appears in the ribbon (“Opt. : grid”). This allows you to add a grid to the SELECTED graphic

How to create your own grid :

You can also add/create your own grids by pressing the “create new grid” button in the Opt. button: grid. This will open a new Excel file in which you can enter your grid with the following nomenclature:

• 1 “full” line (with data) = one point
• between 2 points, the grid will form a solid line
• to separate two unconnected grid segments, leave a “blank” line (no data”)

Standardisation of spider diagrams :

This option allows you to normalise spider diagrams dynamically, a classic approach in geochemistry and the geosciences more generally.

The list of standardisations already included in Better Plot is available here, many thanks to F. Humbert for sharing his personal compilation, from which the majority of the standardisations originate.

How to use it :

When the “Y – spectrum / spider diagram” chart type is selected, a new section appears in the ribbon (“Opt.: normalisation”). This allows you to normalise the data entered in the cells using the formula “=data / normalisation”.

How standardisation works :

Normalisation is achieved by recognising the headers, which must therefore correspond to one of those shown in red in the Normalisation sheet (“show normalisation list” button), for example the “U” header for the element uranium.

Based on this principle, you can add as many custom headers as you like to the Normalisation sheet by adding an extra column based on the same model as the others.

The list of standardisations is shown below. If you wish to add more, simply add an extra line (all columns are not required).
