 How to display x-axis time in seconds format? |

Hello Peter,
In MFC "Realtimemultithread example", how do I display x-axis labels only as values from 0 to seconds instead of displaying them in {value|mm/dd/yy<*br*>hh:nn:ss} format?
For example, I want to display it like this: 0, 1, 2, 3, ...., 10800, 10801, 10802, ....
I tried it like this :
const int sampleSize = 10800;
c->xAxis()->setLinearScale(0, sampleSize, 50);
c->xAxis()->setTickDensity(75);
c->xAxis()->setLabelFormat("{value|ss}");
c->xAxis()->setMinTickInc(1);
viewer->syncLinearAxisWithViewPort("x", c->xAxis());
Thank you in advance.
Best regards
Cho |

Hi Cho,
In the original sample code, there are the following lines:
(1) c->xAxis()->setDateScale(viewPortStartDate, viewPortEndDate);
(2) c->xAxis()->setLabelFormat("{value|hh:nn:ss}");
Please change (1) to:
(1) c->xAxis()->setLinearScale(viewPortStartDate, viewPortEndDate);
and please remove the (2). Line (2) is not necessary for numeric scale.
Best Regards
