Google chart animation loses visibility when chart data changes

I'm having trouble getting Google Chart animations to work properly. I think the problem is that the chart keeps redrawing instead of just updating the data, but based on Google's sample code and my limited knowledge of JavaScript, I'm not sure how to fix this. I don't want to include a button to update the chart because the chart will eventually dynamically update data from the data source. How do I update my chart to properly animate data changes?

MYSQL query to copy all data in a column from one database to another

I accidentally used the "Generate Description" feature on the Opencart SEO tool and it overwrote all of my product descriptions with the product title. I have over 600 products and it would be a pain to remake them all. I have a MYSQL backup from 2 months ago that contains most of the products except about 20 that were added later. I have imported an old backup into a newly created database, what query can I run to copy and overwrite all the description column data from the backup table into the current table? They are located in database.oc_product_descriptio

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
