When you change a graph to a black-and-white graph and input a trend line, it shows the trend line with dots on it. This can occlude the data on the graph and make analysis more difficult. Furthermore, certain funders may request graphs be in black and white. Having dots on the graph indicates that there is data on this line rather than being a visual tool to aid in analysis. I am requesting that this be changed so that the trend line is solid without any dots on it.
