# Value base

Value base is a fast way to transform your query result into different ways of presentation. Basically "Comparison" and "Percentage".

• Comparison: a value point compared to a baseline, what's the delta of change?
• Percentage: a value in percentage comparing to a baseline.

## Options​

Here, we present 4 different baseline options, percentage has on/off binary value. Let's explain what it means with each option:

1. Baseline=Raw, Percentage=OFF: this is raw data of query result, no transformation applied.
2. Baseline=Raw, Percentage=ON: using raw data of query result, but each data point will be percentage value of total (SUM of all data points).
3. Baseline=Mean, Percentage=OFF: compute mean value of current metric, and calculate delta of the data point minus the mean value.
4. Baseline=Mean, Percentage=ON: Same as above, but transform value into percentage using the delta value of its original raw value.
5. Baseline=First, Percentage=OFF: compute the delta value of current data value minus the first data point in the graph.
6. Baseline=First, Percentage=ON: Same as above, but transform value into percentage using the delta value of its original raw value.
7. Baseline=Last, Percentage=OFF: compute the delta value of current data value minus the last data point in the graph.
8. Baseline=Last, Percentage=ON: Same as above, but transform value into percentage using the delta value of its original raw value.
