Chart Recorder Common y-axis

[0110110110110]

I have 3 thermocouple inputs which I output to a chart recorder (as their sample frequency is 1Hz thus block size too low for a y/t chart). These are then displayed one above another with 3 separate y axes and one common x (time). How can I make these display on one common y-axis?

Please see the images below. There are two ways to change from multiple windows to one window ... note that each channel is still plotted against its own y-axis settings, regardless of the axis displayed in the one window mode. 

1- click the one window button on the tool bar

2- use the Display menu to select the one window arrangement.

Brilliant thank you! I'm new to DASYLab and didn't know there were more options like this on these hidden windows.

There are lots of features in the display windows associated with the Y/t Chart, Chart Recorder, X/Y Chart, etc. 

In the one window mode, where all traces are plotted in the same area, you can change the axis display in the Axes menu. 

When you click on the channel's name in the legend below the drawing area, it will change the primary axis to that channel. The axis is color coded, so that you can tell which channel it represents.

The colors and lines feature (the paintbrush button) allows you to change the colors for all elements of the display window. If I use a grid, for example, the default color is too bright for me, so I change it to a more muted color, faded out a bit so that it drops into the background and doesn't compete with the data. 

In addition to the menus and the tool bar, you can double-click on the axes to change that axis, including the x-axis. 

If you make the x-axis width very large, you can zoom in to focus on a smaller area. In the Chart Recorder, you then have a scroll bar to move around the data. 

If you want an asymmetric display, such as two channels on one axis and the third on a different one, explore the Diagram module in Chart Recorder mode. 

If you want drawing space, you can disable the display of the menu and toolbar, and use the Right-click menu to access features. In this case, use CTRL-click and drag to zoom, and CTRL-right click to unzoom. 

Enjoy!
