| Post subject: | datetime at regular intervals |
I have a datetime series on the X axis with about 500 points that range over 4 months Is there a good way to have the X labels be marked at the first day of every month... e.g) 09/01/2010, 10/01/2010, 11/01/2010 I thought of using the LabelSkip parameter but one month of longer or shorter than the next. Any ideas? |

Hi, You can use the LabelingMethod parameter of the drawScale() function. If you set it to LABELING_DIFFERENT it will only prints labels that are different from the last printed one. You'll then have to format your X label serie like : Code: $MyData->addPoints(array("09/01/2010","09/01/2010","09/01/2010","10/01/2010","10/01/2010","10/01/2010"),"Labels"); ..or event better, use the TimeStamp and use the setXAxisDisplay() function to format the output.
