[Article in German] BÃ¶hm M. Adenosine has a negative inotropic effect in cardiac atrial preparations (direct negative inotropic effect). This effect is probably due to an activation of a potassium outward current which shortens the action potential duration and hence reduces the force of contraction.
A scatterplot is a graph that is used to plot the data points for two variables. Each scatterplot has a horizontal axis (x-axis) and a vertical axis (y-axis). One variable is plotted on each axis.
A 3D scatter plot allows the visualization of multivariate data. This scatter plot takes multiple scalar variables and uses them for different axes in phase space. The different variables are combined to form coordinates in the phase space and they are displayed using glyphs and colored using another scalar variable.
