# Statistics

In the Statistics view, you can see statistics on the views processed by the tool. The available data is dependent on the tool output, such as Confidence score or Coordinates.

You can filter the image database The set of images used to train and test your vision application. by selecting the bars on the various charts. Hovering the mouse over a column shows the number of matching images.

Tips for filtering data:

- If you select multiple bars on the same chart, those filters are added together (logical OR).

- If you select bars on different charts, the image dataset is filtered to those views where all of the selected filters are true (logical AND).

- The limit of each bar is calculated based on the values of the X-axis, or domain.

- Statistics help identify anomalies, for example, if any images fall outside the expected count range, selecting the given bar shows the incorrectly processed images and you can manually correct them.

The bar charts use the following colors:

Color | Meaning
| Blue | The active image is part of the statistical category represented by the bar.
| Grey | The actively filtered image is part of the statistical category represented by the bar.
| Light grey | Bars are used for the current filter and the images where the filter expression is true.
| Mid-dark grey | Bars are not used for the current filter and the images where the filter expression is true.
| Dark grey (background) | Images where the filter is false.
