Change chart marker color if there is continuous value higher than a baseline value

Asked 2021-Jun-10 at 07:43

I am currently creating a VBA macro to change the color of the marker of a chart if the value in the chart consists of 3 continuous spikes that exceeds a baseline value of 0.7.

For example, in the picture below, I've create a macro to change all the marker colors to red if the value is higher than the baseline value, but not if there are 3 continuous values higher than baseline value.

My Code

This is what I've tried - changing the marker color to red if the value exceeds 0.7

For that you would need to work with a window size to check always 3 dots in a row if they are above basline if the are color them and move 1 further to check the next 3 in a row.

Create a row index column on the dataset with .I, subset the data for thos 'sub_class' where 'sub_new_I' is 1, get the unique rows by 'firm', 'year', 'subclass', then grouped by 'firm', 'sub_class', create the discounted_I column by taking the lag of negative exp of difference between the next 'year' (lead) and the 'year' divided by 5 ('newdf'). Then, do a join with the original data on 'rn'

QUESTION

Euclidean distant for NON-CONSECUTIVE classes of factors iterated by groups

Asked 2021-Apr-30 at 15:06

This question is an extension of this question. Euclidean distant for distinct classes of factors iterated by groups

The same explanations from the previous question apply here as well. I want to calculate the Euclidean distance between consecutive years for each firm based on patent classes according to the following formula:

Where Xi represents the number of patents belonging to a specific class in year t, and Yi represents the number of patents belonging to a specific class in the previous year (t-1).

The difference here is that I want to add another assumption: If a year/some years is/are missing in between, I want to implement the assumption that the firm has been active in the same patent classes as the latest non-missing year. For example, in the following dataset:

QUESTION

Euclidean distant for distinct classes of factors iterated by groups

Asked 2021-Apr-29 at 16:35

*Update: The answer suggested by Rui is great and works as it should. However, when I run it on about 7 million observations (my actual dataset), R gets stuck in a computational block (I'm using a machine with 64gb of RAM). Any other solutions are greatly appreciated!

I have a dataframe of patents consisting of the firms, application years, patent number, and patent classes. I want to calculate the Euclidean distance between consecutive years for each firm based on patent classes according to the following formula:

Where Xi represents the number of patents belonging to a specific class in year t, and Yi represents the number of patents belonging to a specific class in the previous year (t-1).

To further illustrate this, consider the following dataset:

I believe that the function below does what the question asks for, but the results for Firm == "B" are not equal to the question's.

ANSWER

Answered 2021-Apr-21 at 10:26

To delete the chart title, instead of deleting the The TextFrame2, delete the actual title. Also the delete method will fail if there is no title present.

Check if the chart has title and then delete it. For example try this.
