4. Axis Config + Low/High — Range Column
In this step, the columns returned from the Compass record are bound to the widget's X axis, Low Value, and High Value fields. If Color By Column is optionally selected, a color is assigned to each category. In this flow the Y axis does not appear as a single column — it is split into the Low/High pair.
Wizard route: /cartography/add/axisconfig
Prerequisite
A Compass record must have been selected in Step 3 and the query result loaded.
1. Screen Layout
On the left are dropdowns (X axis, Low Value Column, High Value Column, optional Color By Column); on the right is the Data Preview table.
2. X Axis
| Field | Description | Typical for Range Column |
|---|---|---|
| X Axis Type | Data type of the X axis | CategoryAxis (day, shift), DateTimeAxis (date series) |
| X Axis Column | Query column to bind to X axis | day, date, shift |
3. Low Value Column (Key Field of This Flow)
| Field | Description |
|---|---|
| Low Value Column | Numeric column to bind to the lower boundary of the bar |
The Y axis starts with this field instead of a single column.
If Low Value Column is Empty
If this field is not filled, the Next button gives a warning: "Please select a Low Value column".
4. High Value Column
| Field | Description |
|---|---|
| High Value Column | Numeric column to bind to the upper boundary of the bar |
If High Value Column is Empty
If this field is not filled, the Next button gives a warning: "Please select a High Value column".
Low and High Same Column
If Low and High are bound to the same column, the bar height becomes 0 and it looks like a line. This is undesirable — make sure to select different columns.
5. Color By Column (Optional)
| Field | Description |
|---|---|
| Color By Column | (Optional) Categorical column — a color for each unique value |
When this field is filled, the Assign Colors panel opens below it:
| Category | Color |
|---|---|
| S1 | 🟦 blue |
| S2 | 🟧 orange |
| S3 | 🟩 green |
Color By Scenarios
- Shift-based coloring (S1/S2/S3)
- Product code-based coloring (products A/B/C)
- Device status (OK / Warning / Critical)
Colors Not Being Saved
First select the Color By Column, then assign colors. If the order is reversed, the colors will not be saved.
6. Data Preview Validation
The Data Preview on the right shows that the X / Low / High / Color By columns are correctly bound. Check:
- Is Low ≤ High? (for each row)
- Does the Color By column have 3-8 unique values?
- Is the X column sorted?
7. Confirmation
When you click the Next button at the top right, the axis assignment is validated.
8. Next Step
Steps 5 and 6 Are Skipped
For Range Column, Step 5 (Series Design) and Step 6 (Add Series) are skipped. You go directly to 7. General Design. Color assignment has been done in the Assign Colors panel in Step 4.
