| 29 | <h2>dygraphs number display</h2> | |
| 30 | <p>Dygraphs can display numbers in either scientific mode (fixed number of significant figures) or fixed-point mode (fixed number of digits after the decimal point). It is in fixed-point mode by default.</p> | |
| 31 | <p>To switch to scientific mode, set the <i>sigFigs</i> option to the number of significant figures in your data.</p> | |
| 32 | <p>In fixed-point mode, you can control the number of digits after the decimal using the <i>digitsAfterDecimal</i> option. For particularly large numbers, this format can get unwieldy (i.e. '100000000' for 100M is a bit lengthy). Once the numbers get to a certain length, dygraphs will switch over to scientific notation. This is controlled by the <i>maxNumberWidth</i> option.</p> | |
