[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.
To create a scatter chart, execute the following steps. 1. Select the range A1:D22. 2. On the Insert tab, in the Charts group, choose Scatter, and select Scatter with Straight Lines. Note: also see the subtype Scatter with Smooth Lines above Scatter with Straight Lines.
