Main Issue: I am having a hard time transitioning multiple lines after I shift & push in new data into my data array. interpolate('linear') . The first two coordinates cx, cy represent the center of the viewport; the last coordinate width represents the size of the viewport. D3 multiple Axis interpolation. Basically, what you need to do is set the tooltips to show on each tick of the x-axis data, so instead of grabbing the position of the mouse with mouse[0] and moving the tooltips, you should move it to the position where the x-axis data is. The line. However, it's now "intended to work with d3. Thus, if you would like to show a gap between 2 lines (which actually represent 2 separate lines), you will need to draw them separately. 0 Radial lines Examples · A radial line generator is like the Cartesian line generator except the x and y accessors are replaced with angle and radius accessors. Sequential color schemes are available as continuous interpolators (often used with d3. date); }) . How to draw curved ( interpolated ) line point by point with D3?
